Rationale

Nimbus: an Ethereum 2.0 Sharding Client

Building & Testing

Prerequisites

  • A recent version of Nim
    • We use the version in the Status fork
    • Follow the Nim installation instructions or use choosenim to manage your Nim versions
  • A recent version of Facebook's RocksDB

Obtaining the prerequisites through the Nix package manager

Users of the Nix package manager can install all prerequisites simply by running:

nix-shell nimbus.nix

Build & Install

We use Nimble to manage dependencies and run tests.

To build and install Nimbus in your home folder, just execute:

nimble install

After a succesful installation, running nimbus --help will provide you with a list of the available command-line options. To start syncing with mainnet, just execute nimbus without any parameters.

To execute all tests:

nimble test

Our Wiki provides additional helpful information for debugging individual test cases and for pairing Nimbus with a locally running copy of Geth.

Troubleshooting

Sometimes, the build will fail even though the latest CI is green - here are a few tips to handle this:

  • Wrong Nim version
    • We depend on many bleeding-edge features - Nim regressions often happen
    • Use the Status fork of Nim
  • Wrong versions of dependencies
    • nimble dependency tracking often breaks due to its global registry
    • wipe the nimble folder and try again
  • C compile or link fails
    • Nim compile cache is pretty buggy and sometimes will fail to recompile
    • wipe your nimcache folder
